Norgren L68M-NNP-MRQ Micro Fog Lubricator - Without Yoke
Part Number: L68M-NNP-MRQ
Quick Summary
Norgren L68M-NNP-MRQ Micro Fog Lubricator provides precise lubrication for general pneumatic systems in manufacturing environments. Operators often struggle with inconsistent oil/air ratios as flows change along long pipe runs, leading to uneven component wear and increased maintenance. The Olympian Plus yoke Plug-In system offers modularity that supports scalable installations and future upgrades; it remains compatible with common industry practices and can be configured toward CE-compliant setups and IP-rated enclosures when used with appropriate accessories. By delivering a compact, reliable micro-fog spray and a simple service path, this lubricator helps OEMs reduce waste, extend service intervals, and streamline integration within L68M-series ecosystems for broader cost efficiency.

FAQs
The L68M-NNP-MRQ is the yokeless variant and is designed for streamlined mounting using compatible brackets. For wall mounting, the 18-001-979 wall bracket provides a secure fit, while optional Yoke assemblies Y68A-6GN-N1N/N2N can be added if future integration with a yoke is planned. This setup minimizes footprint and simplifies retrofit projects in tight panels or limited-space cabinets.
The lubricator delivers a steady micro-fog flow with a nominal capacity of 175 dm3/sec and a start point of 6 dm3/sec. A built-in flow sensor maintains a nearly constant oil/air ratio across a range of flows, ensuring consistent lubrication even as line demand varies, which reduces over-lubrication and wear on components.
Yes. The Olympian Plus micro fog design is specifically suited for long and complex piping networks where consistent lubrication matters. The fine mist reduces oil migration losses over distance, while the modular plug-in system supports scalable deployment across multiple zones, helping maintain uniform performance across your entire plant.
Maintenance is straightforward using the L68M-KIT service kit, with a manual drain and quick-fill features facilitating fast level checks and refills. Regular bowl inspection, leak checks, and replacing elastomer seals with nitrile components extend life. The kit provides genuine components to minimize downtime and maintain lubrication accuracy in demanding cycles.
Available accessories include Yoke assemblies (Y68A-6GN-N1N and Y68A-6GN-N2N) for future mounting flexibility, a wall bracket (18-001-979) for fixed installations, and the L68M-KIT service kit for ongoing maintenance. These options enhance modularity, ease of installation, and long-term cost efficiency on L68M-series lubrication solutions.
